A dynamoelectric machine including first and second permanent magnets held by first and second magnet seats on first and second yoke portions so as to face inner circumferential surfaces of tip end portions of first and second claw-shaped magnetic pole portions. The first and second permanent magnets are magnetically oriented in a reverse direction to orientation of a magnetic field that the field coil produces. The dynamoelectric machine enables permanent magnet holding reliability to be increased, induced voltage during no-load de-energization to be suppressed, and thermal demagnetization of magnets due to high-frequency magnetic fields that are induced by stator slots to be avoided.

A parameter adjusting device configured to adjust a great number of parameters of a physical model by a genetic algorithm using multiple processing units within a short time. A parameter adjusting device comprises a processing assignment means wherein a part of a multiple processing means is assigned to search processing by a local search method, and assigns the processing of the local search to a low-performance processor. Also, the parameter adjusting device collects an interim result of the search by a genetic algorithm, and uses it for the search processing by the local search method. Through parallelization and efficiency of an adjusting processing by effectively utilizing the resource in the system, the parameter adjusting device can determine the group of the most appropriate parameters within a short time.

A chromosome using each of a plurality of parameters of a physical model of a semiconductor element as a gene is defined and the parameters are optimized using a genetic algorithm based on the characteristics measurement data of the semiconductor element fabricated by way of trial. In the selection processing of the genetic algorithm, a sum of a first evaluation value based on linear scale data and a second evaluation value based on logarithmic scale data is employed as the evaluation value of the chromosome.

Parameter adjuster

A parameter adjusting device and a parameter adjusting method configured to adjust a great number of parameters used for a circuit design model of a semiconductor element such as a transistor within a short time. A parameter adjusting device adapts a circuit design model wherein a formula for analysis is derived based on a surface potential such as, for example, the HiSIM, as the circuit design model of a semiconductor element; defines a chromosome wherein a respective great number of parameters of the model are genes; and optimizes the parameter based on property measured data of a tested element, using a genetic algorithm. Parameter adjustment comprises a first step adjusting the parameters which determine the structure of the semiconductor element based on the property measured data of a long channel group; and a second step adjusting nonadjusted parameters based on the property measured data of various lengths of channels with reference to a result of the first step. Adjustment of the optimum parameters within a short time and with a high degree of accuracy, which was conventionally difficult, can be performed.

Disclosed herein is a turning zigzag embroidery machine adapted to read in from outside needle center data N, which permits scaling up or down or alteration of an embroidery pattern, and to convert the needle center data into frame center data C to reproduce an embroidery pattern in an improved form. Of externally read-in needle center data N (.DELTA.X, .DELTA.Y, .theta., W) and the data of needle center N on X-Y axes, this turning zigzag embroidery machine transforms, for example, data Nk (Xk, Yk, .theta.k, Wk) of needle center Nk into data Ck (xk, yk, .theta.k, Wk) of frame center Ck on x-y axes by arithmetic conversion. Then, in order to advance an embroidering needle 10 to the needle center Nk, a rotatable frame is shifted in the directions of x- and y-axes and at the same time it is turned through a given rotational angle .theta.=.theta.k in the direction of arrow E. At each of the advanced needle center positions, the embroidering needle is imparted with a rocking motion across a rocking width Wk to make a stitch at a given stitch point Sk, thereby reproducing an embroidery pattern on a cloth.
